Marantz Cinema 40 - 9.4 Channel Network AV Receiver

Marantz Cinema 40 for a serious home theater setup

The Marantz Cinema 40 is a 9.4-channel network AV receiver made for buyers building an immersive home cinema system. It combines high-power multichannel amplification with modern HDMI connectivity, so it fits well in a premium TV-and-speaker setup.

9.4-Channel Speaker Layout

This model supports a 9.4-channel configuration, which gives you room for a large surround setup with multiple height speakers and subwoofers. That makes it suitable for anyone planning a fuller Atmos-style home theater rather than a basic TV audio upgrade.

7 8K HDMI Inputs

The Cinema 40 includes seven HDMI inputs, and Marantz lists them as 8K-capable. That is useful if you want one receiver to handle several source devices while keeping the system ready for modern video formats.

HEOS Built-In Streaming

HEOS Built-in adds network audio and app-based streaming features, including support for whole-home listening. It is a practical match for buyers who want both home theater switching and everyday music playback in the same unit.

Designed for Premium Rooms

Marantz positions this model as a reference-level receiver with a front-panel porthole design, premium materials, and subtle side lighting. The black finish and full-size chassis make it better suited to a dedicated media room or living room cabinet than to compact setups.

Compatibility and setup checks

Before ordering, check that your TV, speakers, and source devices match the kind of system this receiver is meant for. The official specifications list three HDMI outputs with one eARC output, Audyssey MultEQ XT32 room correction, Bluetooth, AirPlay, Spotify Connect, and Roon Ready support.

The supplied package also includes the main unit, remote control, batteries, AM/FM antennas, wire labels, a quick start guide, an Audyssey microphone, a cardboard microphone stand, two external detachable antennas, and an AC cord.
